Recognize these? Here's what usually causes it.
Common Causes
- Drying time set too short for humidity level
- Dock air vents blocked reducing airflow
- Too much cleaning solution creating soap residue
- Not emptying dirty water tank frequently

Step-by-Step Solution
Extend Drying Time
Open the Roborock app and go to dock settings. Find mop drying time and set it to maximum which is usually 3-4 hours. The default may be too short for your climate. In humid areas or during summer extend drying time further. You can also enable hot air drying if not already on.
Clean Dock Air Pathway
The dock blows hot air through channels to dry the pads. Hair and debris can block these channels. Remove the dirty water tank and look into the dock base. Use compressed air or a thin brush to clear any debris from air vents and channels. Blocked airflow prevents drying.

$20.99Reduce Cleaning Solution
Too much floor cleaner leaves residue in mop pads that soap retains moisture and promotes bacteria growth. Use only the recommended amount of Roborock cleaner or less. Some users have better results using just water. Reduce solution concentration and see if smell improves.
Empty Dirty Water Daily
The dirty water tank holds grimy water from mop washing. If left sitting this water grows bacteria that smell. Empty the dirty water tank after every cleaning or at least daily. Rinse the tank with clean water before replacing. Standing dirty water is a major source of odor.
Replace Mop Pads
Mop pad fibers break down over time and hold more water and bacteria. Even with proper drying old pads smell bad. Replace mop pads every 3-6 months depending on usage. Keep backup pads so you can rotate while washing one set thoroughly by hand with bleach.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the robot returns to the dock mid-clean, moved furniture may have invalidated its map — a fresh floor scan resolves the majority of navigation failures.
Remove mop pads after final clean of the day and hang them separately to ensure complete drying if built-in drying is insufficient.
New filter smell is nearly universal with activated carbon — most people assume the unit is faulty when it just needs 24–48 hours at high speed to off-gas.
